Abstract :
[en] Traditional distribution channels that cover nanostores still abound in merging megacities. These traditional retail formats need to be visited and supplied very frequently (High Frequency Stores) which turns to be costly and time consuming if not well optimized. Supplying High Frequency Stores in emerging countries involves different constraints that make the associated optimization problems complex. In this paper, we deal with a real-life application problem where a company try to build an effective strategy to cover and to supply nanostores. We present an altered approach to a multi-depot multiple traveling salesman problem. The problem of concern is modeled as an assignment problem, combined with side constraints regarding disruption of pre-assignments and profit potential balance. The results show that the multi-objective function produces better profit and workload balance than setting a simple objective function and a constraint, one for the profit balance and the other for workload balance and vice-versa.
